1. One of my characters just became a Mediator. How come she can't perform any of the "Talk" skills yet?
The only thing I can think of is that you haven't spent the JP to learn the abilities yet.


2. What do I do with Ramza? He stayed a knight for the longest time until I started messing around with jobs. He moonlighted as a Summoner briefly and then I decided to put him back on knight.
Ramza's Squire job can be pretty good with Scream (he can also learn Ultima if it's cast upon him). I made him a Squire and then gave him Calculator abilities as a secondary skill.

3. How do I take advantage of the "equip armor" skill? My mages have it, how do I exploit it?
Equipping it and equipping strong armor allows your mages to have much higher HP and defense, which can be quite good in most cases.

4. Is it okay just to concentrate on five members? What's the ideal mix of classes?
You'll never have more than five members in a battle, so it's perfectly fine. I like to have two fighters and two casters personally, and replace them with the special characters as I get them.

5. I just started Chap. 2 and one of my characters just became a Lancer. Where can I get a spear for her?
Head up to Igros Castle, they should sell it.
